Description

A kind of A.C. contactor iron core

Technical field

The utility model relates to a kind of iron core, and more particularly, it relates to a kind of A.C. contactor iron core.

Background technology

Iron core, is all generally to make with silicon steel sheet, and in hot-wire coil, it can produce larger magnetic flux density.

The iron core using in throttling contactor is divided into static iron core and moving iron core, produce magnetic field by the coil electricity being wound around on static core, thereby attract moving iron core to make described static iron core and moving iron core closure reach the object of switch, due to its closure, while disconnecting due to the vibration of iron core self cause its loose contact, connect unstable.

At present, the laminated and riveted plug-in iron core that a kind of application number is CN01138900.1 is disclosed on market, it is the left-half that the steel disc that is shaped by punching folds into iron core, the steel disc being shaped by punching folds into the right half part of iron core, on a side interface of the iron yoke of iron core, have groove, on the opposite side interface of the iron yoke of iron core, be connected with the boss matching with groove, boss and groove form to closely cooperate the left-half of iron core and right half part are fixed together.

Although it is more firm, accurate that this iron core connects at the more common throttling contactor iron core of structure aspects, it is only connected by groove, and the frictional force of moving iron core and static iron core is limited, can not well play fixation.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide that a kind of adhesive is stable, A.C. contactor iron core accurately.

For achieving the above object, the utility model provides following technical scheme: a kind of A.C. contactor iron core, comprise static iron core and moving iron core, described static iron core and moving iron core comprise quiet chip and the moving chip of multiple stacking settings, described quiet chip and moving chip all include crossbeam and three suspension columns, one end of described suspension column is fixedly connected sequentially on described crossbeam, wherein: the length of the other end of described suspension column is and is crisscross arranged, and suspension column just right on described static iron core and moving iron core is mutually adaptive, and described static iron core and moving iron core are pegged graft by suspension column.

By adopting technique scheme, described static iron core and moving iron core differ by length and the suspension column grafting of adaptation mutually, when the coil electricity being wound around on static iron core produces the moving iron core of magnetic attraction, described iron core connects more tight, accurate, stable, when anti-stop iron core is fitted on static iron core, produce vibration.

The utility model is further set to: described interjacent suspension column is wrapping post, and only has the length of described wrapping post to be to be crisscross arranged.

By adopting technique scheme, described in only have the different in size of wrapping post, in ensureing iron core stable connection, simplified again the structure of iron core, be convenient to processing and manufacturing.

The utility model is further set to: described any two spaced suspension column length are identical.

By adopting technique scheme, the quiet chip in described same iron core and moving chip only have two kinds of specifications, have further simplified again the structure of iron core in ensureing iron core stable connection, are convenient to processing and manufacturing.

The utility model is further set to: on described chip, offer louvre.

By adopting technique scheme, described louvre has increased the radiating effect of iron core, thereby has reduced the thermal losses of iron core, the vibration having produced while having reduced iron core operation.

Compared with prior art, A.C. contactor in the utility model utilizes the length of wrapping post to be crisscross arranged with iron core, and static iron core and moving iron core are pegged graft by wrapping post is adaptive, make described iron core adhesive more stable, accurate, firm, utilize again the increase of wrapping post face area strengthen in the heat-sinking capability of iron core, reduced the thermal losses of iron core operation.

Embodiment

With reference to Fig. 1, the utility model A.C. contactor is described further with iron core embodiment.

A kind of A.C. contactor iron core, for A.C. contactor, comprise static iron core 1 and moving iron core 2, described static iron core 1 and moving iron core 2 comprise quiet chip 3 and the moving chip 4 of multiple stacking settings, described quiet chip 3 and moving chip 4 all include crossbeam 5 and three suspension columns 6, one end of described suspension column 6 is fixedly connected sequentially on described crossbeam 5, described interjacent suspension column 6 is wrapping post, described wrapping post is for winding around, after described coil electricity, thereby described static iron core 1 can move iron core 2 described in the adhesive of generation induced field, preferably, the length of the other end of described wrapping post is and is crisscross arranged, as described in Figure of description, be divided into long chip 8 and short chip 9 by the length of described wrapping post, and suspension column 6 just right on described static iron core 1 and moving iron core 2 is mutually adaptive, described static iron core 1 and moving iron core 2 are pegged graft by suspension column 6, described any two spaced suspension column 6 length are identical, on described chip, also offer louvre 10 and riveted holes 11, described quiet chip 3 and moving iron core 2 are riveted together by riveted holes 11 separately.

Pass through said structure, described static iron core 1 and moving iron core 2 produce after induced field at static iron core 1, differ and the wrapping post grafting of adaptation mutually by length, described iron core connects tightr, accurately, stable, when anti-stop iron core 2 is fitted on static iron core 1, produce vibration, described only have the different in size of wrapping post, and described any two spaced suspension column 6 length are identical, quiet chip 3 in described same iron core and moving chip 4 only have two kinds of specifications, in ensureing iron core stable connection, further simplify again the structure of iron core, be convenient to processing and manufacturing, described louvre 10 has increased the radiating effect of iron core, thereby reduce the thermal losses of iron core, the vibration having produced while having reduced iron core operation.

The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
